Game Photos: Bears Vs. Bengals

"I thought we did a great job competing," Tillman said of his man-to-man matchup with Green Sunday.

Green was targeted 13 times, catching nine passes for 162 yards and a pair of touchdowns in the Bengals loss to the Bears.

"He made some unbelievable catches. I see him doing that to a lot of teams the rest of his career, special kid," Tillman said.

Tillman, 33, was so gassed covering Green he was vomiting on the sideline and needed an IV, pedialyte and coconut water for dehydration.

Tillman was held out of individual drills in practice Wednesday with a sore knee, but both he and head coach Marc Trestman said it was just a precaution, and expect No. 33 to play Sunday against Minnesota.

No rest for the weary though -- Tillman will be one of eleven Bear defenders trying to stop Vikings running back Adrian Peterson.

"He's in a league of his own, another elite player in this game," Tillman said. "Our defense will have their hands full."
